Friction and Gravity

Third Experiment Hula hoop
Friction and gravity apply to my experiment by, while hula hooping and stopping my body I am the unbalance force that acts upon the hula hoop making the hula hoop move downward towards the ground because of gravity.

Problem-If I am hula hooping for one minute long the same paste and I all of sudden I stop would it take longer than 3.3 seconded to the gowned?

Hypothesis-In my option I think that if I stopped automatically then I think that it will take 3.5 sec to reach the grown because of gravity, It will bring the hula hoop down.

Newton's laws
Newton's first law an object at rest will remain at rest. Then object that is remaining at rest is the hula hoop because once it hits the floor it will need someone to pick it up because the object will not move unless someone moves it. The seconded part of Newton's first law is a object in motion will remain in motion same direction unbalanced force acts upon it. The object that is in motion is, myself because I am moving my hips. I have to move my hips because if I don’t then the hula hoop will just drop to the floor. Newton's seconded law; greater the force, the greater the acceleration. That means the more force I put on the hula hoop the faster the hula hoop will go.

Materials
Myself
2 Timer
Hula hoop
And another person to time

Procedure
1. Gather all materials.
2. Make sure you have two timers in your hands.
3. Take the first time watch and once you start hula hooping start the timer.
4. When it close to one minute give the person a 10 seconded warning and get ready to start once it hits a minute .
5. When the whole minute is up stop with the timer and make sure the person that are timing does not move then start with new timer when they are done hula hooping
6. Make sure to recorded your timings
7. Now that was the first one now all you have to do is make sure you have two timers in your hands.
8. Take the first time watch and once you start hula hooping start the timer.
9. When it close to one minute give the person a 10 seconded warning and get ready to start once it hits a minute .
10. When the whole minute is up stop with the timer and make sure the person that are timing does not move then start with new timer when they are done hula hooping
11. Now you have two tests done and you just have to do one more tests and that is exactly what we did up there
12. Make sure you have two timers in your hands.
13. Take the first time watch and once you start hula hooping start the timer.
14. When it close to one minute give the person a 10 seconded warning and get ready to start once it hits a minute .
15. When the whole minute is up stop with the timer and make sure the person that are timing does not move then start with new timer when they are done hula hooping and now you are all done with you test!


Identifying Variables
CV- same person that is hula hooping, same hula hoop, same timers, same people that are timing,
DV- the gravity
IV- the speed
Control- the type on hula hoop

My results
My result showed that gravity will take over because, well it is the earth and is shows that there is gravity on the earth. If we didn't have gravity in life then there would be a lot of conflicts in the world trying to get to place to place.

Observations
I saw that while I was doing my experiment that the gravity will always pull down toward the ground usually, never up. Also I have notice that it takes a shorter amount of time to hit the floor than I thought.

My hypothesis
My hypothesis was wrong and right because it actually took a shorter amount of time than 3.3 seconds. I was right about gravity will bring the hula hoop go down because if we didn't have gravity on this earth then there would be no way of getting basket balls, baseballs, tennis balls, soccer balls edc., out of the sky. So that’s good if we have gravity.
